An optional configuration file to separate sensitive data can be placed at `${DIR_ENVIRONMENTS}/${ENVIRONMENT}-private.yml`. Configuration is available to steps with the function `GetEnvironment()`. |
 | DIR_SCHEMAS | ./schemas | Directory where the JSON schemas are available. These JSON schemas are used by some steps to validate some output (e.g. the body of the HTTP response). |
 | DIR_ENVIRONMENTS | ./environments | Directory where the configuration for each environment is available. Each environment must have a yml file in this directory. |
 | LOG_DIRECTORY | ./logs | Directory where logs are written. There may be multiple log files. Currently, there is one for tracing the execution of the steps and scenarios (golium.log) and another one to save the HTTP requests and HTTP responses (http.log). |
